java 用类方法编写的例子

public class Jifen {int jifen;String leixing;public void show() {if (jifen >= 1000 && "金卡".equals(leixing)) {System.out.println("回馈积分500分");} else if (jifen >= 5000 && "普通卡".equals(leixing)) {System.out.println("回馈积分500分");} else {System.out.println("对不起没有积分回馈!");}}}

import java.util.Scanner;public class Text5 {/** * @param args */public static void main(String[] args) {// TODO Auto-generated method stubScanner input = new Scanner(System.in);Jifen a = new Jifen();System.out.println("请输入积分:");a.jifen = input.nextInt();System.out.println("请输入卡的类型:");a.leixing = input.next();a.show();}}
